How Signal Modulation Works
Wireless technologies like WiFi and cell phones rely on modulation to transmit data simultaneously without interference. By using a Fourier transform, engineers can shift signals from the complex time domain into the frequency domain, where they appear as distinct spikes or spectrums.
Making High Resolution Counter and Voltage Measurements with your Oscilloscope
Keysight’s InfiniiVision oscilloscopes reduce bench clutter by integrating a 3-digit voltmeter (DVM) and a high-resolution 10-digit counter/totalizer. These tools operate through standard probes but function independently of the trigger system, providing high-precision frequency measurements up to 3.2 GHz and versatile DVM modes (AC, DC, RMS) in a single, “6-in-1” instrument interface.
Keysight Technologies Introduces Next-Generation Triple-Output Power Supplies
The new Keysight E36300 Series triple-output DC power supplies offer 80W to 160W of high-stability power with a 4.3” color display for simultaneous channel monitoring. Designed for both pros and students, they feature data logging, low-current measurement (80 uA), and BenchVue software integration to simplify complex design testing at an affordable price point.
Real-Time or Sampling Oscilloscope – Key Comparisons
Selecting the best oscilloscope depends on understanding two primary categories: Real-Time and Sampling (Equivalent-Time). While they overlap in frequency ranges, their core architectures serve very different engineering needs.
The piezoelectric effect and oscilloscopes
The piezoelectric effect can cause unexpected signals on an oscilloscope when the device or probe is physically bumped. Ceramic capacitors inside the scope act as piezoelectric materials, generating small voltages from vibration. While this effect is real, it rarely impacts actual measurements thanks to rigorous testing and robust design—so unless you’re measuring on a vibrating surface, there’s nothing to worry about.
